Should I be running my 1999 Nissan Pulsar SLX on E10 petrol or premium unleaded?
Nissan says only models post 2004 can run E10, which isn’t a lot of help for owners of older models like yours. The 1999 Pulsar hatch has multi-point fuel injection, so there’s little chance of you having a problem with E10. If you were concerned about the effects of E10 you could run premium unleaded.
